You would need elevated privileges, at least of user 2000 (shell) or higher. Since the Android is not rooted, your best bet is to get adb running in wireless mode in your device. You would also have to load a compatible adb binary for your Android to connect to localhost via adb.

Once this have been achieved, run

adb shell screencap /sdcard/FILE_NAME.png

  • Is this exclusively from adb? I tried from the actual phone (on 2 different devices) with a terminal app with $ screencap test.png and it generates a 0 byte file. The folder is writable, for example echo hello > test.txt does create a 6 byte file

    Yes. You need adb. User installed (unprivileged) apps cannot capture screen without using dedicated API.
